The Rudolph Research J57TPN refractometer is intended for use in hospital pharmacies and Compounding Labs to monitor the quality of parenteral nutrition mixtures, Intravenous therapy (IV), and ensure compliance with USP<797>. It is also useful in preventing the diversion of narcotics, and other controlled materials. The J57TPN pharmacy refractometer provides a fast, easy to use way to check on materials returned from the operation theatre or incorrectly issued from the pharmacy. The J57TPN shares many features with the entire Rudolph Research Refractometer Product Line.
The Rudolph J57TPN refractometer features a fully automatic measuring system. The operator simply places the sample on the prism, presses a button and the result is displayed on a 7.5cm x 10cm back-lit digital LCD screen. There are no shadow lines to match and there is no eyepiece requiring operator determination or manual adjustment.
The J57TPN has built-in comparison and calculations for fast and accurate measurements of substances. The user enters the % Dextrose and % Amino Acid and the refractometer will display both the calculated and measured result, making it easy for an operator to see if the material is within specification.
